Homework Statement
A car accelerates at 2.0 m/s^2 along a straight road. It passes two marks that are 30 m apart at times t = 4.0s and t = 5.0s. What was the car's velocity at t = 0s?
Homework Equations
There are some equations in the chapter that I have used for previous homework problems but for this one I'm not sure which one or ones to use.
(Vf)^2 = (Vi)^2 + 2ad
(d = distance)
a = vf - vi/t
d = vt + 1/2a(t)^2
The Attempt at a Solution
I have tried finding the initial velocity at t = 0s but I can't seem to find a way to utilize the other variables.
Thanks.
